In order to provide access to .spo files SPSS has an application called the "Legacy Viewer," which is the SPSS 15.0 SmartViewer with the licensing stripped off. If you wish to view and edit output created in the versions of SPSS that created .spo files, please install the Legacy Viewer and open the older output using that application. Legacy Viewer is on the installation CD and also available from Ida.

This problem should be fixed by running the Microsoft Visual C++ redistributable which is included with the install at C:\Program Files\IBM\SPSS\Statistics\22\VC9\Vcredist_x86.exe (32 bit) or C:\Program Files\IBM\SPSS\Statistics\22\VC9\Vcredist_x64.exe (64 bit)
